Abstract: A flexible oximeter device for measuring pulse and blood oxygen saturation in tissue includes a first array of first light emitting elements that emit red light, a second array of second light emitting elements that emit green light or near-infrared (NIR) light and an array of sensor elements arranged on at least one flexible substrate. Each sensor element is configured to detect red and green or NIR light, and to output a signal representing an amount of red or green or NIR light detected. The first and second arrays and the array of sensor elements form a plurality of interleaved measurement pixels, each pixel comprising one of the first light emitting elements and a corresponding sensor element, and one of the second light emitting elements and a different corresponding sensor element.

Abstract: A data processing method and a client is provided. When obtaining a first data packet and a second data packet of a target call service, a client classifies the first data packet into a first data packet set and classifies the second data packet into a second data packet set based on a first time segment and a second time segment, where a first obtaining moment of the first data packet belongs to the first time segment, a second obtaining moment of the second data packet belongs to the second time segment, the first time segment and the second time segment are different time segments. Furthermore, the client calculates, audio and/or video quality corresponding to the first data packet set, and audio and/or video quality corresponding to the second data packet set.

Abstract: A zeolite catalyst from ZSM-5 modified with phosphorus, rare earth elements and pore structure regulator is used for methanol/dimethyl ether conversion to light olefins.High temperature, non-recycling, continuous-running process is realized in the reactor system, comprising a dehydration reactor and several (2-n) adiabatic, fixed bed cracking reactors, loaded with the catalyst in multi-stage packing and operated in reaction regeneration cycles. The catalyst possesses high activity, high selectivity, good hydrothermal stability and long reaction life time.Operation of 100% methanol conversion and >85% C.sub.2 -C.sub.4 selectivity has been performed in a reactor system of the scale 0.7-1 ton CH.sub.3 OH/day for >600 hours on stream and with reaction time of single cycle >24 hours.
